Hi
I wonder if somebody can please advise me on why Calibre doesn' want to download on my laptop? I used to have it on my pc but i changed to windows 7 home premium and i deleted it. I have tried to download it multiple times, and from diffrent mirrors and sites and i always get the same pop up:

"the installation package could not be opened. Contact the application vendor to verify this is a valid windows installation package"

i have disabled my AVG and my windows firewall. I thought it could be a problem with the windows but i downloaded itunes and adobe and some other programs and i did register the product.

any advise would be appreciated, I have looked at other ebook management but Calibre is the best!!!!
